This mostly reverts commit 849a3700 ("block: avoid ordered task state change for polled IO"). It was wrongly claiming that the ordering wasn't necessary. The memory barrier _is_ necessary. If something is truly polling and not going to sleep, it's the whole state setting that is unnecessary, not the memory barrier. Whenever you set your state to a sleeping state, you absolutely need the memory barrier. Note that sometimes the memory barrier can be elsewhere. For example, the ordering might be provided by an external lock, or by setting the process state to sleeping before adding yourself to the wait queue list that is used for waking up (where the wait queue lock itself will guarantee that any wakeup will correctly see the sleeping state). But none of those cases were true here. NOTE! Some of the polling paths may indeed be able to drop the state setting entirely, at which point the memory barrier also goes away. (Also note that this doesn't revert the TASK_RUNNING cases: there is no race between a wakeup and setting the process state to TASK_RUNNING, since the end result doesn't depend on ordering).

Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security Pull integrity updates from James Morris: "In Linux 4.19, a new LSM hook named security_kernel_load_data was upstreamed, allowing LSMs and IMA to prevent the kexec_load syscall. Different signature verification methods exist for verifying the kexec'ed kernel image. This adds additional support in IMA to prevent loading unsigned kernel images via the kexec_load syscall, independently of the IMA policy rules, based on the runtime "secure boot" flag. An initial IMA kselftest is included. In addition, this pull request defines a new, separate keyring named ".platform" for storing the preboot/firmware keys needed for verifying the kexec'ed kernel image's signature and includes the associated IMA kexec usage of the ".platform" keyring.

Multipathing: In case of NFSv3, rpc_clnt_test_and_add_xprt() adds the xprt to xprt switch (i.e. xps) if rpc_call_null_helper() returns success. But in case of NFSv4.1, it needs to do EXCHANGEID to verify the path along with check for session trunking. Add the xprt in nfs4_test_session_trunk() only when nfs4_detect_session_trunking() returns success. Also release refcount hold by rpc_clnt_setup_test_and_add_xprt().

It's OK to sleep here, we just don't want to recurse into the filesystem as a writeout could be waiting on this. Future work: the documentation for GFP_NOFS says "Please try to avoid using this flag directly and instead use memalloc_nofs_{save,restore} to mark the whole scope which cannot/shouldn't recurse into the FS layer with a short explanation why. All allocation requests will inherit GFP_NOFS implicitly." But I'm not sure where to do this. Should the workqueue be arranging that for us in the case of workqueues created with WQ_MEM_RECLAIM?

If a reply has been processed but the RPC is later retransmitted anyway, the req->rl_reply field still contains the only pointer to the old rpcrdma rep. When the next reply comes in, the reply handler will stomp on the rl_reply field, leaking the old rep. A trace event is added to capture such leaks. This problem seems to be worsened by the restructuring of the RPC Call path in v4.20. Fully addressing this issue will require at least a re-architecture of the disconnect logic, which is not appropriate during -rc.

Having to specify "proto=rdma,port=20049" is cumbersome. RFC 8267 Section 6.3 requires NFSv4 clients to use "the alternative well-known port number", which is 20049. Make the use of the well- known port number automatic, just as it is for NFS/TCP and port 2049. For NFSv2/3, Section 4.2 allows clients to simply choose 20049 as the default or use rpcbind. I don't know of an NFS/RDMA server implementation that registers it's NFS/RDMA service with rpcbind, so automatically choosing 20049 seems like the better choice. The other widely-deployed NFS/RDMA client, Solaris, also uses 20049 as the default port.
